The Microsoft LifeCam HD-3000 doesn't support having it's exposure set in this manner.

We've had 0 problems with exposure control on the HD-3000 camera, and are actually quite happy with it so far.
From personal experience and research, I think that the LifeCam doesn't preserve its settings after a power cycle, and, because you can't configure the settings from the RIO, it makes it difficult to have a configured camera on a robot. Usually. Some people, probably including you, wt200999, seem to have LifeCams that just work. They preserve their settings after a power cycle where other LifeCams would not. After hours of digging through Google search results, I haven't found the reason why.


OP -- The way our team solved the problem was by plugging the LifeCam into a Raspberry Pi 2, where we were able to configure its settings live using v4l2. We, however, didn't stream that camera to the dashboard, instead choosing to keep the stream on the Pi for vision processing.
